Sometimes Iceland really lives up to its name. For instance, in the picture above, the entire country is basically covered in snow and ice. With one notable exception. See that big black dot in the middle? No, not in the lower left--that's the largest natural lake in Iceland, Lake Þingvallavatn, which is a favorite for snorkelers and scuba divers. We're talking about the beauty mark in the center-right, which is an absolutely massive lava flow originating from a fissure of the volcano Bárðarbunga.
